Is Musk's $1m-a-day cash giveaway to US voters legal?
  • Musk isn't giving everyone a million dollars. He's giving people lottery tickets, and they might be worth a million dollars but are far more likely to be worthless.

    You can buy such lottery tickets yourself, and they cost about the same as a cup of coffee.

  • Tesla Bet On 'Pure Vision' For Self-Driving. That's Why It's In Hot Water
  • Everyone thinks they know.

    But the autopilot on an aircraft or ship is often just a cruise control, maintaining a constant heading, speed, and (for aircraft) altitude. The pilot or skipper remains 100% responsible for course changes and collision avoidance.

  • What is a *salt* and what is a *bleach*?
  • When salts dissolve in water, the resulting ions are surrounded by layer of water molecules known as a "solvation shell". Water molecules are polar, so they are attracted to ions for the same reason ions attract each other. Dissolved ions can travel through water freely but will remain surrounded by the solvation shell until something else binds to the ion.

    So it's fair to say that a dissolved ion is more attracted to water molecules than to salt molecules. When a salt precipitates, the opposite is true.

    Finally, a mixture of dissolved salts has the properties of its ions but no "memory" of the original salts. In other words, if you mix a solution of NaCl with a solution of KNO3, the result is the same as mixing solutions of NaNO3 and KCl.

    EDIT

    Bonus trivia: solvation shells are critical to how your neurons and muscle cells send electrical signals. Cellular electrical currents are carried by ions, including Na+ and K+. Cells need to distinguish those ions. How? The K+ solvation shell is larger than that of Na+. So cells conduct Na+ with pores that allow Na+ through but are too small for K+.

    But what about selectively conducting K+? For that, the ion enters a ring that is the same size as the K+ solvation shell. The ring simultaneously grabs and rips off all the water molecules, so the K+ ion can pass through a tiny pore without its solvation shell. The Na+ solvation shell is too small for the ring, so the solvation shell cannot be grabbed and ripped off. Thus the Na+ ion cannot get through the tiny pore.

  • US startup charging couples to ‘screen embryos for IQ’
  • IQ is your performance on an IQ test. It's not subjective at all, for the same reason that SAT math scores are not subjective.

    The real question is whether SAT scores and/or IQ scores have anything to do with what we consider "intelligence".

  • Kamala Harris appears to say Israel is committing genocide in Gaza
  • Hi, I heard you like to cite Wikipedia.

    Antisemitism[a] or Jew-hatred[2] is hostility to, prejudice towards, or discrimination against, Jews.[3][4][5]

    Due to the root word Semite, the term is prone to being invoked as a misnomer by those who incorrectly assert (in an etymological fallacy) that it refers to racist hatred directed at "Semitic people"

  • It sure looks like Trump watches are breaking copyright law
  • "When working for them" means "when they pay you". The point is that the corporation must financially compensate the artist. That's how copyright makes art into a livelihood.

    Without copyright, corporations can use art without ever paying the artist at all.

  • Kentucky man declared brain dead wakes up during organ harvesting
  • Once the heart stops beating, the organs fail. Including the heart itself.

    That's kind of the point of defining brain death. Normally death is declared after the heart stops beating. In brain death, the heart is beating but the brain is not receiving any blood.

  • Kentucky man declared brain dead wakes up during organ harvesting
  • She was caring for him for three years.

    You cannot be brain dead for three years. Brain death is legal death. Once you are declared brain dead, you are officially a cadaver and won't be going home. You are going to the morgue that day, with possibly a brief initial stop in the operating room if you're an organ donor.

  • It sure looks like Trump watches are breaking copyright law
  • Without copyright, the artist would be unemployed. Because the corporation he now works for could just take his photos without paying him.

    Copyright protects his livelihood. And THAT is one massive reason why copyright is necessary.

  • Fani Willis asks appeals court to reinstate charges against Trump
  • They didn't all go poof.

    • Fani Willis indicted Trump and his crew with 41 charges.
    • The judge said 6 of the 41 were too vague, the other 35 could proceed to trial.
    • Willis is trying to get those 6 added back to the 35.
  • Should democrats prioritize progressives or moderates?
  • Not all moderates are Dems. Many are independents.

    I see plenty of leftists saying things like "I refuse to vote for Democrats".

    I see plenty of moderates saying things like "I usually don't vote the Democrats but this time I will".

    It makes more sense for Democrats to appeal to the latter then the former.

  • Biden sets out new Israeli proposal to end war in Gaza

    www.bbc.com Israel-Gaza war: Biden sets out new Israeli proposal to end conflict - BBC News

    US president urges Hamas to accept the three-phase plan, saying "it's time for this war to end".

    Israel-Gaza war: Biden sets out new Israeli proposal to end conflict - BBC News

    Ending the Gaza war: Three phase proposal

    PHASE ONE

    • It would begin with a six-week ceasefire, during which the IDF would withdraw from populated areas of Gaza
    • Hamas would release "a number" of hostages - including women, the elderly and the wounded - in exchange for hundreds of Palestinian prisoners. Some remains of dead Israeli hostages would be returned to their families
    • Palestinian civilians would return to their homes in all areas of Gaza
    • Humanitarian assistance would "surge", with 600 trucks a day entering the strip, and hundreds of thousands of temporary housing units sent by the international community

    During that six week period, negotiations mediated by the US and Qatar would continue. If successful, the next part of the plan would begin.
